Definitions
- Still another object of the present invention is to provide a film suitable for the packaging of medical solutions characterized by high mechanical strength.
- polymer generally includes homopolymers, copolymers and terpolymers and blends and modifications thereof.
- ethylene propylene copolymer is used herein to refer to a copolymer formed from polypropylene monomer and minor amounts, usually less than 6%, of ethylene.
- modified and the like is used herein to refer to a polymeric material in which some or all of the substituents are replaced by other materials, providing a change in properties such as improved flexibility or elastomeric properties.
- modified ethylene propylene copolymer the modification is provided by a rubbery block copolymer such as commercially available under the trade-mark Kraton from the Shell Chemical Company.
- Adhesive layer 42 is preferably made from a blend of modified ethylene propylene copolymer and very low density polyethylene.
- a suitable blend is for example a blend of 50% of the modified ethylene propylene copolymer (such as the Cosden Z4650 material) and 50% of the very low density polyethylene (an especially suitable commercial resin is DEFD 1137 available from Dow Chemical Company).
- Other polymeric materials or blends of polymeric materials may also be used for interior layer 42 to the extent that the moisture barrier, flexibility and other essential characteristics of the film material are not substantially affected, and provided of course that sufficient adhesion is provided between intermediate layer 44 and sealant layer 40.
- Intermediate layer 48 may be the same VLDPE as in layer 44; or a different VLDPE material.
- Various polymeric materials or blends of materials may be used for adhesive layer 50 provided that the material used imparts sufficient adhesion between outer layer 52 and intermediate layer 48.
- the preferred material for layer 50 is a modified ethylene vinyl acetate copolymer with a carboxylic acid or acid anhydride functionality.
- An especially preferred commercial resin is Plexar 3382 available from du Pont.
- Another suitable commercial modified EVA resin is CXA E162 available from du Pont.
- An EMA-based anhydride & modified polymeric adhesive may also be used.
- the films as described are preferably manufactured by a cast coextrusion process.
- Example 9 the multi-layer film comprised the same construction as the films of Examples 3 through 8, but produced at a pinch roll speed of 7.9 m per minute (26 feet per minute) to make a 0.38 mm (15 mil) tubing.
